T0 all 'whom it muyv concern:

Be it known that l, FREDERICK D; MILLI- GAN, a citizen of the United States, and a resident of San Diego, county of San Diego, and State of California, have invented certain new and useful improvements in Brakes for House-Moving Trucks, of which the following is a specification.

My invention relates to adjustable and automatically operated brakes for house moving trucks and the principal objects of my invention are, first, to provide a brake that may be attached to any house moving truck with but slight alterations, second, to provide a brake that is automatic and positive thus reducingthe liability of accidents, third, to provide a brake that will facilitate the labor of house moving, especially over rough and rolling ground, and, fourth, to provide a brake that is adjustable, economically constructed and easily operated.

With these and other objects in view as will hereinafter appear, my invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a part of this specification, in which:

Figure l is a plan view of my device complete attached to an ordinary house moving truck which is shown by `dotted lines, and showing a portion of the brake supporting bracket broken away to facilitate the illustration, and Fig. 2 is a side elevational view thereof.

Similar characters of reference refer to similar parts throughout the several views.

The brake supporting bracket 1, brake beam 2, brace 3, brake shoe 4, cushion spring 5, release spring 6, staff 7, release lever 8 and operating cable 9, constitute the principal parts of my device.

The brake supporting bracket l is U shaped and it is constructed as shown and is rigidly secured to the top and bottoni side of the truck body which is shown in dotted lines, by means of the bolts la; the other end of this bracket is provided with a tapped hole lb adapted for the threaded portion of the staff 7. This supporting bracket is reinforced at the top by a brace 3 which is rigidly secured at one end to the top of the truck body and at the other end to the top of the brake supporting bracket. A. brake beam 2, is placed between the upper and lower edges of the brake supporting bracket 1, and is constructed as shown. At each end ofl this brake beam 2 is rigidly secured a brake shoe 4.-, which is secured thereto by' means of the bolts a passing through the lugs ab. These brake slices are adapted to conform tothe outside diameter of the wheels ofthe truck. as shown. This brake beam 2 is pivotally mounted at its center on' the staff 7. This staii' 7 is provided with a threaded portion 7 l adapted for the tapped hole 1b. @n the eXtreme end of this threaded portion 7 a is rigidly secured a crank 7b adapted to adjust the brake beam relatively to the wheels. The other end of this staff 7 is provided with a piece 7c which holds the one end of spring 6 in place. Located near the edge of the brake supporting bracket l and between the end of the truck and the brake beam 2 is pivotally mounted on a pin 8LL a release lever 8, one end of which is adapted to bear on the brake beam 2, near the staff 7. The other end is provided with a short rod 8b which is pivotally mounted thereto. The other end of this rod 8b is attached to one end of a turn buckle 8, to the other end of which is pivotally attached a cable 9, which is secured to the same pulling mechanism that ispulling the truck.

Though l have shown and described a particular detailed construction and ar-` rangement of parts, T do not wish to be limited to this particular construction and arrangement of parts, but desire to include in the purview of my invention the principles and construction substantially as set forth in the appended claims.

It is obvious that if the cable 9 is secured to the same pulling mechanism that moves the truck when it is moving forward, the cable 9 will cause the release lever 8 to force the brake beam 2 back, thus disengaging the brake shoes from the truck wheel and allowing the truck to be moving freely, but if the said truck should start ahead faster than the speed of the pulling mechanism, there would be no strain on the release lever, and the tension spring 5 would thrust the brake beam forward applying the brake shoes to the truck wheels, thus preventing va collision between the truck and pulling mechanism, and that by shortening the distance between the washer 7d and the piece 7 c of the. staff 7 the brake beam will be forced from the Wheels 'of the truck, thus allowing the truck to be readilyy moved about when not in use.

It is readily seen that With .this Aconstrucr. tion there is provided a device that will obviate the` necessity of blocking the Wheels of'thetruck when going down a hill, thus avoiding the possibility ofdama-ging the'.

house, that there is provided a device that will facilitate the amount lof labor in moving a house,. that thereis provided a device thatl can be attached-.to any house moving truck with` but slight changes, that there is'fprovided `a `device that is economically.y constructed, easily operated and positivein its action,-thatfthere is provideda device-that vvillireducev the dangenof accidents, that `mighthappenin trying.` to block the WheelsI of. the truck in going down an incline.

Having ithus described myinvention, `vvhat I claim as new' and desireto secure by-.Letf` ters vPatent is:

l.: 'Ar brake for housexmovingitrucls comprising i a U-shaped, support kextending horibrakeushoes mounted on saidbeam, springl and shaft means .mounted in s said lU-shaped support and in connec'tionwvith.` said brake beam for thrustingithe brake shoesy against the .vvheelstof thentruck, 'fa lever pivotally* mounted on said truck with one end engaging with said brake beam for shifting it fromsaid position, means for adjusting the tensionof said brake beam relatively to its support, and means in connection with said lever means adapted to be connected to the truck hauling means.

2. Abrake for house moving trucks comprising a U-shaped support secured to the rear end of a house moving truck, and eX- tending backwardly therefrom, a shaft provided With threads on one end engaging with the threads in a hole in the upward extending end of said U-shaped support, a handle for turning said shaft, a brake beam mounted on'said shaft guided by the horizontal members of said U bar, a thrust spring on said shaft engaging with saidbeam tending to Ithrust it forward, brake shoes on said brake beam adapted to engage with the Wheels on said 1 truck, a lever pivotally mounted on said U support 'with one `end engaging with said brake beam, and a cable attached to 'its other end adapted to be Vconnected tothe truck hauling means.

Inftestimony whereof, I have hereunto subscribed my name'in the presence of two subscribing Witnesses.
